Abstract—With the increasing demands for adaptive middleware of dynamic systems in pervasive computing environments, the need for dynamic software architecture and programming infrastructure to achieve dynamic adaptation is widely recognized. In this paper, we firstly present a semantic and adaptive middleware architecture called ScudWare that supports for dynamic and heterogeneous environments. ScudWare middleware is based on adaptive communication environments, which consists of adaptive components, and semantic virtual agents. Specially, a ScudADL framework and the specification semantics, based on higher-order typed ¼ calculus theory, are proposed, which describes ScudWare component structure characters, and dynamic behavior adaptation. In the ScudADL, the computing resources consumption is concerned. And the component inner and outer adaptive behaviors are separated from component functional behaviors in an explicit way. Finally, we introduce an application of ScudWare architecture, which is a computer aided assessment system in a smart CAA space, and give a case study to show its adaptation.

Index Terms—adaptive middleware, smart CAA space, architecture description language, higher-order typed ¼ calculus
